Referring in detail to the drawings, the numeral 10 indicates a portion of a roof such as the roof of a building which may be a house or the like, and the roof 10 is provided with an opening 1 1, Figure 3. The numeral 12 indicates a base which has a plate portion 13 that is inclined and the plate portion 13 is arranged contiguous to the upper surface of the roof 10. The plate portion 13 is provided with an opening 14 which registers with the opening 11 in the roof 10. The base 12 further innited States Patent 0 ce 2,885,944 Patented May 12, 1959 2 cludes a continuous upstanding wall member 15, and the wall member 15 includes rear and front portions 16 and 17 which are arranged in spaced parallel relation with respect to each other, and the wall member 15 fur-` ther includes spaced parallel side portions 18, Figure 4.

The dormer ventilator of the present invention includes a cover or top member which is indicated generally by the numeral 19, and the cover 19 includes a rectangular top wall 20 which has an inclined front wall section 21 extending therefrom, and also depending from the sides ofthe top wall 20 are inclined side wall sections 22. The cover 19 is provided with rearwardly disposed inclined support portions 23 which abut the plate portion 13 of the base 12. Extending inwardly from the lower edges of the wall sections 21 and 22, are horizontally disposed wall surfaces 24 which are provided with inner upstanding portions or lips 25.

Positioned below the cover 19 is a louver which is indicated generally by the numeral 26, and this louver 26 is illustrated in perspective in Figure 7. The louver 26 includes inclined side wall sections 27 and a front inclined wall section 28, and extending outwardly from each of these wall sections 27 and 28 are flanges 29, and arranged on the rear of the louver 26 are inclined support portions 30 which abut the plate portion 13 of the base 12. Spaced parallel posts 31 extend upwardly from the front portion of the base l2 and are secured thereto, and the posts 31 are L-shaped in cross section, and the flanges such as the ilanges 29 are adapted to be secured to the posts 31 as for example by means of securing elements 32. T he lower portion of the louver 26 is shaped to include horizontally disposed wall surfaces 33 which terminate in upstanding portions or lips 34.

Positioned below the louver 26 is a louver 35, and the louver 35 is smaller than the louver 26. The louver 35 has substantially the same construction as the louver 26. Thus, the louver 35 as shown in Figure 8, includes a front inclined wall section 36, and inclined side wall sections 37, and there is further provided on the louver 35 upstanding portions or flanges 38 which are secured to the posts 31 as for example by means of securing ele- In Figure 9 there is illustrated a lower louver which is indicated generally by the numeral 42, and the lower louver 42 includes an inclined front wall section 43 as well as inclined side wall sections 44, and the louver 42 includes upstanding portions or flanges 45 which are adapted to be secured to the posts 31. Inclined support portions 46 are arranged on the rear portion of the louver 42, and the louver 42 includes lower sections 47 which abut the plate portion 13.

There is illustrated in Figure l0 a reticulated or screenlike body member which is indicated generally by the numeral 48, and the body member 48 is adapted to be used for preventing insects, birds, and the like from working their way through the ventilator and passing through the openings 14 and 11 into the attic or buildfor use in supplying fresh air to attics, or upper portions" of buildings. In use, the parts of the ventilator are adapted to be constructed and arranged as shown in the drawings, and it will be seen that the base 12 has its plate portion 13 inclined and abutting the upper surface of the roof 10. The base 12 is provided with the opening asstra/t4 14 which registers with the opening 11 in the roof 10. The reticulated body member 48 is arranged so that it prevents insects, birds, and the like from entering through the openings 14 and 11, and the body member 48 may be secured to the posts 31 as for example by means of suitable securing elements. The ventilator includes the upper louver or cover 19 which includes the top wall 20 as well as the sections 21 and 22, and the cover 19 further includes the inclined rearwardly disposed portions 23. There is further provided the intermediate louvers 26 and 25 as well as the lower louver 42. All of these louvers have substantially the same construction, but each is of a different size so that the louvers can be arranged in superimposed fashion and this construction is such that the front sections of the louvers are arranged over each other, while the side sections of the louvers are also arranged in alignment with respect to each other and these side sections are spaced apart and are arranged in overlying or overlapping relation with respect to each other. This has the practical effect of providing a means whereby airA can pass through the spaces between the louvers and then through the reticulated body member 48 so that fresh air can enter the top of the building through the openings 14 and 11. By having the side sections and front sections of the louvers arranged in overlying or overlapping relation with respect to each other, it will be seen that in the event of rain or snow or the like that the rain will be kept out of the interior of the ventilator so that such rain will not work its way or nd its way into the building through the openings 14 and 11.

The parts can be made of any suitable material and in different shapes or sizes.

Thus, it will be seen that there has been provided a dormer ventilator which is extremely attractive in appearance and which also provides increased ventilation whereby attics can be ventilated more eiciently. The louvered sides of the Ventilator as well as the louvered front portion provide the required means whereby air can enter the attic. The lower louver 42 is adapted to be secured in place to the base 12 and the other louvers are mounted above the lower louver in such a manner that an air ventilation space is left between the louvers, and the corner posts 31 can be used for helping support the various parts of the ventilator. The screened body member 48 prevents unwanted insects, objects and the like from entering the ventilated area. Air can pass through the space between the sides of the louvers as well as the space between the fronts of the louvers so that increased ventilation is provided for pitched types of roofs. The ventilator can be made of small size and the various louvers can be made of sheet metal and the body member 48 can be made of screen material. The opening 14 in the base 12 is arranged over the opening 11 in the roof 10 and the base 12 may be fabricated from a single piece of suitable material such as a piece of sheet metal. Thev parts are made so that they conform to the pitch or contour of the roof. The louvers are set at such an angle that any rain or the like which contacts the louvers will be carried off by gravity towards the outer part of the ventilator and then toward the lower portion of the pitched roof, and the louvers may be secured in place in such a manner as to provide a watertight seal with the roof. The louvers increase in length as they progress upwardly, that is the lower louver is shorter in length than the next louver thereabove, and so forth. The number of louvers used may be varied as desired, depending uponthe amount of ventilation required as well as the size of the device or the shape of the roof. Suitable water-proofing material may be used wherever necessary or required. The rear support portions of the louvers are adapted to be secured to the plate portion 13 of the base 12 in any suitable manner, while the front portions of the louvers and the front portion of the cover 19 are secured to and supported by the posts 31. The upstanding wall member 15 helps to insure or prevent any water which may be blown into the spaces between the louvers, from passing down through the openings 14 and 11. If desired, suitable drainage apertures or openings can be provided wherever necessary, and the outer portion of the base 12 may be used to provide a ashing to keep out water and for securing the ventilator to the roof.
